| Popis: | In the article, the structure of a bench for testing the friction characteristics of a friction pair of centrifugal brake rollers has been considered. The dependences of the coefficient of friction and wear on the temperature of the materials of the friction pair, viz., a brake insert manufactured by Huzhou Jiutong Logistics Machinery Co., Ltd (China) and a domestic friction pair of the 6KV-10 rolled brake band of the EM-2 grade over St.3 steel grade (A537Gr.58), were obtained for temperature ranges that do not exceed 100°C. It has been shown that the rubber–PA6 friction pair widely used in brake rollers of foreign manufacture cannot be employed at high values of the slip velocity and the normal force applied to the friction lining, as it results in rapid heating to the critical temperature and, as a consequence, intensive wear. The domestic 6KV-10 brake band of the EM-2 grade, along with a metallic roller shell is proposed as the material of the friction pair. The frictional material proposed for the friction lining has a high coefficient of friction and a high wear resistance in a wide range of operating temperatures, normal forces, and temperatures of the frictional contact. |
